Starting new topic.Out of curiosity.

 I have a sneaking suspicion that it is the CCM that has given up the ghost.Going on the computer hook up Wednesday.

 If I buy a two socket VW/Seat/Skoda CCM with a different part number,can't find one with the exact number,can it be coded to my Octavia?Even if the plugs are not exactly in the same position as on the existing one? 

Well if part numbers differ the connector pinout also might differs although the connector looks the same sou you would need to rearrange pins. It can be coded for your car but with limitation, when I say limitation I mean the power windows controller will not operate because of lack of communication with CCM.

For example, if you have 1J0 959 799AH CCM and you replace it with 1C0 959 799AH CCM, your power windows won`t work and you have to replace power windows controllers on all doors to match you new CCM.

So the best bet is CCM with same part number.

Thanks for the reply.That's out the window then.

 Talking of windows,I gave up and took the auld jaloppy to a garage.The guy ran a diagnostics,and tells me there is only 5v+ on the red/yellow wire,where there should be 12v+. But as he was  trying to sort the brakes he didn't have the time to work on it as I need the car at 4am tomorrow morning.Next week,or I may go for a bypass via a couple of relays.

  Non operative drivers door window is an NCT fail.Unless I leg it out of the test center just before the inspector gets in,disconnect,reconnect the earth cable,then I have a ten minute window in which the window works
